From e269998d588f8ad96eaf86916e23b8ee3d2b9f1b Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 17 Aug 2017 10:02:09 +0200 Subject: ASoC: codecs: msm8916-wcd-analog: get micbias voltage from dt This patch adds bindings in DT to provide required micbias voltage which could be specific to board. With this new binding, now the mic bias voltage is left at hardware default value if the device tree does not specify any mic bias voltage value. Correct micbias value is required for mbhc buttons to work.
